It has been said before, but I will join the chorus of those recommending an all-region Blu-Ray/DVD player. They are relatively inexpensive and will forever remove the guesswork of whether a disc will play or not.

I fully agree. I don't understand why so many collectors seem hesitant to get an all-region player, given the riches of film releases (often in better prints) that await in Europe, Australia and Asia. The BFI and Eureka alone can empty your wallet
